unable to claim festival crates from the store

tried to check out, relog, restart pc, change browsers, etc. and cannot claim these crates at all

 

Three questions:
1. Have you received the selection before? (Did you order the 3 Royal crates before and this is a second attempt)

2. If you have ordered the crates before, have you opened them yet in-game?

3. If the first two are not your case, have you tried using a different device to login and claim? (Laptop doesn't like website UI sometimes, but my mobile does.)

 

now im having a similar problem

 

Same issue, is the promotion over and the crates just still on the store perhaps?
